The present invention relates to a porous silica composite powder having a mixture of pentaerythritol derivatives and water adsorbed and trapped on the porous silica and having a moisturizing and water retention capability. It may further comprise 2-octyl dodecanol or glycerin, in particular, to further improve the water retention of the composite powder showing a high initial moisturizing feeling, high moisturizing power and high water retention even in a dry environment By adsorbing 2-octyl dodecanol on the surface of powder, it relates to a composite powder having a high initial moisturizing feeling, moisturizing power, high water content, high water retention power and high water content at the same time.

The stratum corneum of the skin protects the body from harmful substances from the outside, and serves to keep the skin moist by inhibiting the evaporation of moisture in the skin to the outside. However, due to the deterioration of the function of the stratum corneum due to the aging of the skin, it is easy to feel the dry skin due to the moisture escape from the skin, moreover, this tendency is prominent in the dry season or winter season.

For this reason, many moisturizers have been developed to improve the dryness of the skin. Representative examples include water-soluble moisturizers and ceramides. Water-soluble moisturizers such as amino acids, organic acids, urea, etc. are used as the most common moisturizers because they have excellent ability to absorb water and provide moisture to the stratum corneum. However, in the dry environment with low humidity, such as winter, not only does the moisturizing power significantly decrease, but also the moisture content decreases rapidly due to low moisture retention in the dry environment. There is a problem as a moisturizer. In other words, glycerin has a high water content and exhibits moisture retention by structurally containing moisture and air in the stratum corneum, but in a dry environment, glycerin has a moisture content in the air. Relatively less, there is a problem that the actual moisturizing power is lowered by the rapid loss of structural glycerin structural moisture in a dry environment, the formulation stability is poor when using a large amount to overcome this disadvantage, glycerin in a dry environment It is difficult to serve as a moisturizer because of the low moisture content it can contain.

In addition, even when glycerin is applied to the formulation, it is difficult to apply it to the formulation because of its incompatibility with the oils used in the formulation when it is applied to an oil dispersion formulation such as a lipstick formulation. Although it adopts a method of forced dispersion by high speed mixing, there is still a low formulation stability, and there are many problems to use because of the disadvantage of incompatibility with other oil to apply a high content.

Ceramide is an important component of intercellular lipids in the stratum corneum of the skin and shows excellent effects on maintaining skin moisture by strengthening the skin barrier function, but it is less compatible with oils used in cosmetics and thus stability of formulation when applying effective content This is difficult to use apart.

Therefore, even in a dry environment, it has a high content of moisture in the stratum corneum and epidermis, shows high moisturizing power and high water retention, and shows excellent effect on the moisture retention of the skin and is compatible with oils used in lipstick makeup cosmetics. It is necessary to develop the present invention, and Korean Patent Application No. 10-2004-0024704 discloses a pentaerythritol derivative which is a new type of moisturizing agent. However, pentaerythritol derivatives are limited in their use due to their low content for use on the skin alone, and also have difficulty in reducing formulation stability. In addition, Korea Patent Application No. 10-2005-0094794 improved this to develop a new type of moisturizer trapped in porous silica, but the water retention capacity in dry environment is improved compared to glycerin, but the water content is lower than glycerin. In addition, it is difficult to show the effect in the lipstick formulation which is an oil dispersion formulation.

Meanwhile, mesoporous porous silica is one of mesoporous molecular sieves, and is a mesoporous molecular sieve in which mesopores of uniform size are regularly arranged. In 1991, a new type of mesoporous molecular sieve materials, named M41S family, manufactured by Mobil researchers using ionic surfactants as structural derivatives, was described in US Pat. No. 5,057,296. And 5,102,643 and the like, research on such mesoporous molecular sieve materials is now actively conducted worldwide. Unlike the synthesis of conventional molecular sieves, these mesoporous molecular sieves are characterized by pore by controlling the type, concentration and synthesis conditions of the surfactant used as a template material during the synthesis process through the liquid crystal templating mechanism. It has the advantage of controlling the size of 16 ~ 100Å, through which various types of materials are being developed.

U.S. Pat.Nos. 6,027,706, 6,054,111 and 1998, Volume 279, page 548 disclose mesoporous materials prepared using amphiphilic block copolymers, which are nonionic surfactants. Is disclosed. In the case of zeolites, one organic / inorganic molecule is generally made by inducing a pore structure, whereas a mesoporous material is formed by a micelle structure in which a plurality of surfactant molecules are aggregated instead of a single molecule to form pores. do. Surfactants are composed of hydrophilic heads and hydrophobic tails, and are known to form various types of self-assembled micelles and liquid crystal structures in aqueous solutions depending on concentration and temperature. The hydrophilic portion located on the surface of the micelle or liquid crystal structure and the precursor of the inorganic material may interact to form an organic / inorganic nanocomposite and remove the surfactant to obtain a material having a mesoporous pore structure. Mesoporous materials differ from zeolites or AIPO-based materials with micropores with a pore size of 1.5 nm or less, and the pore size extends into the mesopore range (2-50 nm). Application of molecular sieve materials to adsorption and separation of large sized molecules, catalytic conversion reactions, etc., which has been limited in the application of materials, has become possible. These mesoporous materials with regular pores also have a very large surface area (> 700 m ² / g), as well as microporous zeolites, which have excellent adsorption properties for atoms or molecules, but unlike zeolites, the size of pores is constant so that It is applied as a support | carrier of catalyst activators, such as a metal compound and amine oxide.

Therefore, the present inventors overcome the initial water content decrease and low water retention when the pentaerythritol derivative, which is a moisturizer, is used as a lipstick-type cosmetic, and the formulation stability can be secured by maximally utilizing the water content of the pentaerythritol derivative itself. In order to develop a new powder type moisturizing cosmetic, the mixture stabilized by mixing pentaerythritol derivative and water in a manner similar to a conventional dry coating process is adsorbed on porous silica having many pores, more preferably mesoporous silica and High initial moisture by adsorbing 2-octyl dodecanol to the surface of the porous silica trapped and adsorbed with the mixture, which can collect and secure compatibility with oil in the formulation of lipstick cosmetics and water retention. Maintain high content of moisturizing, high Formulation of lipstick cosmetics by simultaneously imparting moisture, high water content and high water retention and confirming formulation stability, and further comprising 2-octyl dodecanol or glycerin in a mixture of pentaerythritol derivative and water. It confirmed the compatibility with the oil or increase the water content to complete the present invention.

Accordingly, an object of the present invention is to provide a porous silica composite powder having a high initial moisturizing feeling, moisturizing power and water retention by adsorbing and trapping a mixture of pentaerythritol derivative and water onto porous silica having many pores.

Another object of the present invention is to provide a porous silica composite powder further comprising 2-octyl dodecanol or glycerin in a mixture of the pentaerythritol derivative and water.

It is still another object of the present invention to ensure high compatibility with oil in the formulation of lipstick cosmetics by adsorbing 2-octyl dodecanol on the surface of porous silica adsorbed and collected by the mixture. It is to provide a porous silica composite powder having a water content, high moisturizing power, high water retention and high water content.

In order to achieve the above object, the present invention relates to a porous silica composite powder having a mixture of pentaerythritol derivative and water adsorbed and trapped in the porous silica having a moisture retention and water retention, in order to have a high water retention and water retention The mixture of the pentaerythritol derivative and water may further include 2-octyl dodecanol or glycerin, and in particular, water of the composite powder exhibiting high initial moisturizing feeling, high moisturizing power and high water retention even in a dry environment. In order to further improve the retention capacity, 2-octyl dodecanol is adsorbed on the surface of the composite powder to simultaneously obtain a high initial moisturizing feeling, moisturizing power, high water content, high water retention and high water content. It is about.

Hereinafter, the present invention will be described in more detail.

The present invention relates to a composite powder having a mixture of pentaerythritol derivative and water adsorbed and collected on porous silica, more preferably mesoporous silica having a pore diameter in the range of 2 to 50 nm of silica internal pore. In order to have high water content, high water retention, and high water content, the mixture of pentaerythritol derivative and water may further include 2-octyl dodecanol or glycerin.

The composite powder according to the present invention is a mixture of the pentaerythritol derivative and water is adsorbed and collected on the porous silica, or further comprises 2-octyl dodecanol or glycerin in the mixture of the pentaerythritol derivative and water. Adsorbed and collected, the state fixed to the surface of the porous silica is called 'adsorption', and the state contained in the pores of the porous silica is defined as 'capture'.

The pentaerythritol derivative used in the present invention is a compound represented by the following Chemical Formula 1, which is known from Korean Patent Application No. 10-2004-6024704, and serves to improve the moisture retention ability of the stratum corneum when applied to the skin. .

[Formula 1]

[Wherein R is an alkyl group containing 1 to 24 carbon atoms, saturated and unsaturated, straight and branched chain containing or without hydrogen or hydroxy groups identical or different from each other; m is 0 to 10, n is 1 to 10, the same or different integers.]

In addition, the present invention may further include 2-octyl dodecanol or glycerin in addition to the pentaerythritol derivative and water.

The water used in the present invention may be any of ionized water, distilled water or ultrapure water. In addition, the pentaerythritol derivative may contain up to 42% water, water is contained in 0.1 to 42% by weight relative to the total weight of the pentaerythritol derivative and water, and the water content is adjusted according to the purpose of use and the formulation to be applied. Can be.

That is, the mixing ratio of the pentaerythritol derivative and water in a stable state is mixed in a range of 9: 1 to 6: 4 on a weight basis, and more preferably used in a range of 9: 1 to 7: 3. When the mixing ratio is less than 9: 1, that is, less than 10% of moisture, the water holding capacity is decreased, and in the region having a mixing ratio of more than 6: 4 water, the formulation stability is lowered, and rather, the water holding capacity is lowered. Due to the trapping in the pores of the porous silica and there is a problem that is not evenly adsorbed on the surface of the porous silica.

In addition, the mixture of pentaerythritol derivative and water may further include 2-octyl dodecanol or glycerin, and the mixture of pentaerythritol derivative and water may further include 2-octyl dodecanol. The mixing ratio of the three components (Fig. 1) and the mixing ratio of the three components further comprising glycerin in the mixture of the pentaerythritol derivative and water (Fig. 2) proceed in a region where each of the three components are mixed in a stable state, and each of the three components The stable region of is illustrated in FIG. 1 to further include 2-octyl dodecanol, and FIG. 2 illustrates that glycerin is further included.

Referring to point A in FIG. 1 as an example, when the maximum weight of each is 10, 2-octyl dodecanol is mixed in a ratio of 7, pentaerythritol derivatives 2.5, and water 0.5. The point is A point.

Referring to point A in FIG. 2 as an example, when the maximum weight of each is 10, pentaerythritol derivative is 6, glycerin is 1, and water is mixed at a ratio of 3, which is point A.

In the case where the pentaerythritol derivative and the water further contain 2-octyl dodecanol, since the three components are stable within the range of the maximum water content of the pentaerythritol derivative, the water is the penta. 0.1 to 40% by weight based on the total weight of the three components of erythritol derivative, 2-octyl dodecanol and water.

The mixing ratio of the three components, that is, pentaerythritol derivative, 2-octyl dodecanol and water in a stable state is mixed in the range of 3-8: 2-6: 0.1-4 by weight. , More preferably in the range of less than 10% moisture, mix within the range of 3 to 7.5: 2.5 to 6: 0.1 to 1.0, and mix in the range of 4-5: 4-5: 1 in the range of 10% moisture, 15% of moisture. In the region, the mixture is mixed within the range of 3 to 4: 4 to 5: 1 to 1.5. Circles shown in FIG. 1 are ratios in which a stable region of a three-component system of pentaerythritol derivative, 2-octyl dodecanol, and water is confirmed through experiments.

When the pentaerythritol derivative, 2-octyl dodecanol, and water are out of the mixing ratio, they do not exhibit a stable state in a transparent state without layer separation suitable for preparing the composite powder according to the present invention, and in a suspension state. It stays and changes shape in two directions. The first one is transparent in two phases, but the separation of layers occurs. When applied in the formulation, the water retention and formulation stability of the formulation are significantly lowered. The second phase is in one phase. Maintaining the suspension, high viscosity causes problems in the capture and adsorption process in the porous silica.

When the pentaerythritol derivative and the mixture of water further contained glycerin, the pentaerythritol derivative contained up to 42% water, but the water content was increased due to glycerin having a high water content, and the water contained the pentaerythritol derivative, 0.1 to 45% by weight based on the total weight of the three components of glycerin and water.

The mixing ratio of the three components, that is, pentaerythritol derivative, glycerin, and water in a stable state is mixed in the range of 5 to 9: 0.1 to 1: 0.1 to 4 by weight, and more preferably 8 to 10% of water. ~ 9: 0.1 ~ 1: 1 mixed, in the range of water 20%, 7 ~ 9: 0.1 ~ 1: 2 in the range, 6 ~ 9: 0.1 ~ 1: 3 in the 30% moisture Mix in, and mix in the range of 5-9: 0.1-1: 4 in the 40% moisture range. Circles shown in FIG. 2 are ratios in which a stable region of a three-component system of pentaerythritol derivative, glycerin, and water is identified through experiments.

When the pentaerythritol derivative, glycerin, and water are mixed in a mixed ratio, they do not exhibit a stable state in a transparent state without layer separation suitable for producing the composite powder according to the present invention, and are transparent in a two-phase state in a suspension state. Layer separation appears, which shows a drawback in that the water retention and water content of the formulations are significantly lower when applied in the formulations.

Outside the weight ratio range, since the mixture is present outside the porous silica pores, that is, on the particle surface, the water retention is somewhat lower than the case where only the pores are collected, and the formulation stability is lowered.

A mixture of pentaerythritol derivative and water in the above; A mixture consisting of pentaerythritol derivative, 2-octyl dodecanol and water; Or a mixture consisting of pentaerythritol derivative, glycerin and water; in order to improve water retention of the adsorbed and collected porous silica composite powder and to give compatibility with oil and wax components used in the makeup cosmetics of lipsticks. Only 2-octyl dodecanol can be adsorbed to the porous silica composite powder in which the mixture is adsorbed and collected in the range of 1: 0.2 to 1.0, more preferably 1: 0.3 to 0.8 based on the weight. have. When the 2-octyl dodecanol is out of the weight ratio range, there is a problem in that the moisture retention capacity is lowered or the ability to absorb the moisture present in the surroundings is significantly lowered, thereby decreasing the moisturizing power.
